Connection of electronic medical devices in ICU according to the standard 'MIB'.

In the daily routine of an SICU, particularly in cardiac surgery, the nurses are to an increasing extent confronted with problems of connecting and using medical instruments as well as with documentation of the data of these instruments. An increasing number of user errors is to be expected. Use of advanced computer technology can help avoid such errors. In this paper the system 'ALODIN' is presented which is developed in our institutions according to the IEEE standard 'Medical Information Bus' (MIB). ALODIN-I will be part of a CCCS (computerized critical care system) which is installed in the clinic for cardiovascular surgery at Medical School Hannover.

L-thyroxine treatment of diffuse non-toxic goitre evaluated by ultrasonic determination of thyroid volume.

The effect of a daily dose of 150 micrograms l-thyroxine for one year was studied in forty-five patients with diffuse non-toxic goitre. Thyroid volume was evaluated by ultrasonic scanning. A decrease in the median value of the thyroid volume of about 20% was found after 3 months of therapy and no further change in the median value was observed in the following 9 months of treatment. About 50% of the patients showed a response to therapy and about 30% obtained normal size of the thyroid gland. Median value of the thyroid volume returned to pretreatment value 3 months after thyroxine therapy was stopped. A considerable increase in serum T4 and free T4 index was noted after 3 months of therapy and these elevated values persisted unaltered during the following 9 months of treatment. Serum T3 was studied before and after 3 months of thyroxine therapy in eleven of the patients. A small and insignificant increase in serum T3 and free T3 index was observed.

Sulfamethizole-induced inhibition of diphenlhydantoin, tolbutamide, and warfarin metabolism.

The influence of sulfamethizole on the metabolism of diphenylhydatoin (DPH) tolbutamide, and warefarian is examined. In 8 patients DPH means half-life (T/2) increased from 11.8 plus or minus 3.6 hr to 19.6 plus or minus 5.2 hr and mean metabolic clearance rate (MCR) decreased from 43.7 plus or minus 16,8 to 28.1 plus or minus 9.1 ml/min durus or minus 1.2 to 9.2 plus or minus 1.2 hr MCR decrease from 17.0 plus or minus 5.4 to 10.5 plus or minus 1.2 ml/min. In 2 patients warfarin T/2 increased fron an average of 64.7 to 92.7 hr and MCR decreased from 1.65 ml/min to 1.05 ml/min. In 4 patients on long-term DPH treatment after 1 wk on sulfamethizole inhibits hepatic metabolism of DPH, tolbutamide, and warfarin.

LH and FSH in serum after intramuscular administration of LH/FSH-releasing hormone in normal and hypogonadal men.

The increase in serum concentrations of LH and FSH after intramuscular administration of LH/FSH-RH was investigated in normal and hypogonadotrophic hypogonadal males. LH and FSH were measured by specific radio-immunoassays. To evaluate the appropriate dose of LH/FSH-RH for intramuscular administration different doses were administered and with 200 mu g an increase in LH and FSH was found comparable to the results obtained by other investigators using intravenous administration. After the initial studies a simple test including two determinations before LH/FSH-RH administration and one 60 min and 120 min after administration was developed and used in all cases. In 12 normal males a significant increase in the serum concentration of both LH and FSH was found averaging 381% and 148% respectively 60 min after 200 mu g LH/FSH-RH with a slight decrease in LH but not in FSH after 120 min. A positive response similar to that in normal men was observed in 11 hypogonadotrophic hypogonadal patients presenting different clinical pictures. This indicates that in all these patients the hypogonadotrophic state was due to a hypothalamic defect and not to a hypophyseal disorder.

Effect of probenecid on the excretion of ampicillin in human bile.

1. Ampicillin concentrations were determined in serum and bile after intravenous injection into patients with T-tube bile drainage of 1 gram ampicillin before and during probenecid medication. The concentrations were followed up to fifteen hours after injection.2. Probenecid increased the half-life of ampicillin in serum from 74 minutes to 137 minutes.3. Ampicillin concentrations in bile were higher following probenecid medication and a concentration over 5 mug/ml was obtained for 3 h longer than before probenecid.4. The ampicillin concentrations in bile were approximately the same as those in serum both before and during probenecid medication suggesting passive transport of ampicillin from blood to bile.5. A combined treatment of ampicillin and probenecid might be of clinical value in the therapy of cholangitis and typhoid carriers.
